Residual stress measurements in bevel gear after different production phases

This article discusses residual stress measurements by means of electrochemical removal of material layers with residual stresses and simultaneous measurement of strain on the opposite specimen side with strain gages. Exact measurements are impossible particularly because of the small bevel gear module. With the method presented, the average residual stresses in the tooth root plane and underlying layers are measured. Residual stress distribution after each consecutive production phase is plotted and analyzed. Residual stress measurements enable the engineer to adequately assess each individual production phase and by that improve the quality of the complete production process.     

GL—2型Φ600mm螺旋选别攀枝花钛铁矿生产实践

攀矿选钛厂设计采用传统的螺旋选矿设备ＦＬＸ一１型φ６００ｍｍ螺旋选矿机和φ１２００ｍｍ螺旋溜槽，从选矿（铁）厂磁选尾矿物料中回收原生粒状钛铁矿积累了多年生产实践经验。而广东有色金属研究院研制的ＧＬ一２型φ６００ｍｍ螺旋选矿机具有处理能力大、分选效率高、选别粒级宽、不需冲洗水及占地面积小等特点，有取代选钛厂目前使用的螺旋选矿设备之趋势。

Sheet molding compound characterization using spiral flow

Sheet molding compound (SMC) is a fiber‐reinforced polymeric composite. It is often used in automotive, marine, and industrial applications over other materials because of its high strength to density ratio, resistance to corrosion, and low cost. There is a demand in the SMC industry to be able to characterize SMC processability. This is particularly true for heavy truck body panels, one of the fastest growing applications of SMC. Because of their large size and high strength requirement, the molding forces have a major influence in the molding cycle. Also because of the long flow paths involved, the ability of the paste to carry glass needs to be properly characterized when developing new SMC materials. In this article, we demonstrate the benefits of using spiral flow as a processability tester. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008     

WDB620高强钢应用于大型蜗壳的焊接制造工艺研究

2005年初,水电十四局承担了漫湾二期水电站和小湾水电站蜗壳的制造任务。蜗壳钢材选用国产600 MPa级别高强钢,为了全面综合地考核该级别钢种的材料强度和安全裕度,检验模拟大型蜗壳焊接制造工艺的可靠性。对国产的WDB620高强钢进行了可焊性和制造工艺性试验研究,并在国内首次设计、制造模拟压力容器并对其进行水压试验和爆破试验。研究成果通过中国水电集团公司鉴定,结论为该课题研究成果达到国内选进水平。
